DRILL.

SPECIFICATION forming part of Letters Patent No. 263,359, dated .August29, 1882.

Application filed August 16. 1881.

To all whom it may concern:

Be it known that we, GEORGE NV. RUDE, JonN R. RUDE, and HORACE G. Sworn,of Liberty, Union county, Indiana, and JOHN L.

ltr'lER,of Brownsville, Union county,Indiana, have invented new anduseful Improvements in the Feed Mechanism for Grain-Drills; and we dohereby declare the following to be a full and complete description ofthe same, refer- [o ence being had to the accompanying drawings,

forming part of our application.k

Our invention relates to that class of graindrills known as force-feed,and the novelty consists in the mechanism combined and ar- 1 5 ranged inthe manner hereinafter described.

In the accompanying drawings, Figure l is a rear view of a seed-cup andits interior working parts. 2 is a vertical section,-in side elevation,taken through the line Y Y, Fig. l.

zo Fig. 3 is a horizontal section through the line Z Z, Fig. 2, andtaken in the plane of the sliding shalt. Fig. 4 is a view of the slidingcutolf. Fig. 5 is an enlarged View, in section, showing the manner offastening the cnt-off to the sliding shaft.

A and A are the walls of the seed-cup.

Bis the feed-wheel, journaledin the bearing c. This wheel isnon-adjustable-that is to say, it does not slide laterally to allow agreater or 3o less quantity of grain to be sown, butremains in astationary position in that respect.

O is the cut-ofi' for limiting` the supply of grain to the feed-wheel.This cut-off, which is almost semicircular in cross section, with reverse edges, is so formed that it neatly fits the circumference of thefeed-wheel B, and when adjusted entirely covers said wheel and closesthe feeding-throat of the cup. The turning back of the edges of thecut-ott' in reversed o curves enables the breast of the cut-off to forma closer joint with the feed-wheel, and better prevents the grain fromescaping past such edges than would be the case if the edges were notturned back.

E is a guide cast onto and made part of the out-off, and is forguidinginitslateral motion, and also serves to hold thecut-off in itsproper position. It is for this latter purpose that the guide-piece ismade to extend out so much 5o farther than the cut-off itself. Aperturesare (Model.)

ca-stlin the walls of the seed-cup in order to allow this guide to workback and forth.

D is the horizontal feed-wheel sliding shaft, to which is attached thecut-oft' G in the following manner: The out-off has a ring, E', 55 castwith it, and this ring encircles the sliding shaft, there being,however, between it and the shaft -a removable sleeve, F, having a ange,j', on one of its ends. Eyes or apertures are out into this sleeve,through which 6o a spring-key, P, is inserted. The sleeve is taper-ing,and may be made in halves, as shown, for convenience of handling, or itmay be of one whole piece, as desired. The pin P penetrates the sleeveand sliding shaft, thereby fastening the cut-off to the shaft in aneffective manner.

W is a Washer, which,with the flange of the sleeve F, forms a guidewayembracing ring E', and prevents any sagging motion that might 7o takeplace. The object of this method of fastening the cut-off is to afford aready means of attaching or of replacing the cut-off in case it shouldhe broken or injured in any manner. All that is necessary to be doneisto draw the pin P out, slip the washer from its place, and removethesleeve. This will allow the cut-off to be detached and replaced with onethat is u nin j ured by drawing out the shaft sufficiently.v

H is a hub or swell on theinterior of one of 8o the walls of theseed-cup, and this hub, as will be seen, is of smaller diameter than,athe feedwheel. This is for the purpose of admitting the grain to boththe periphery and end of the feed-cup, thus securing a more perfect flowof the grain.

Sis the vertical tube forming part of the cup. This tube is out away, asseen at d, Fig'. l, so as to form an oblique discharge. AThe grainpasses from thefeed-wheel to this oblique 9o discharge, and thence intothe inclined tube T, to which is fastened the rubber tube for conveyingthe grain to the hoes. The tube S has a flange, U, and the inclineddischargetube'has a flaring mouth, upon the inner sides 95 of which arelugs L and L, which fit over the ange upon the tube S, thus forming aflexible lock by which both are connected and held together.

It will be observed that the end wall ofthe roo cup opposite the hub Hhas an enlarged opening, a, Fig. 2, to prevent the cramping of thefeed-shaft.

Have thus i'ully described our invention, We claim- 1. The combination,with the rotating nonadjustahle scalloped Wheel cylinder, of the feedcup or ease having the swell H upon its inner side adjacent to the endof the Wheel, and of the laterally-moving cut-oli slide, substantiallyas described, for the purpose speciiied.

2. The combination, with the rotating nonadjustable scallopedWheel-cylinder, of the feed cup orcase having the swell upon its innerside, the cnt-olil slide having the curved portion C, with the back orreversed-curved edges, the narrow guiding-extension E, projectingforward from the part G, so that when thelatteris drawn back sonstouncover the wheels said ex tension will guide the cut-off withoutobstructing the feed, and the ring E', and the shaft to which the slideis secured.

3. The combination, with the ring E of the cnt-off slide, of theremovable two-part sleeve F F, having the anges f, the washer YV, theperforated shaft D for operating the cut-offs, and the pin l?, passingthrough the two-part sleeve and the shaft, and operating to hold thering E of the cut-oli' tightly clamped between the flan ge j' of thesleeve and the washer W, substantially as described.
